NOTICE - The following device(s) are recommended alternatives:

The 72T1855 is a 4K x 18 / 8K x 9 TeraSync 2.5V FIFO memory with clocked read and write controls and a flexible Bus-Matching x18/x9 data flow. Bus-Matching TeraSync FIFOs are particularly appropriate for network, video, telecommunications, data communications and other applications that need to buffer large amounts of data and match busses of unequal sizes. There are two possible timing modes of operation with these devices: IDT Standard mode and First Word Fall Through mode.

  • Program programmable flags by either serial or parallel means
  • Big-Endian/Little-Endian user selectable byte representation
  • Auto power down minimizes standby power consumption
  • Master Reset clears entire FIFO
  • Partial Reset clears data, but retains programmable settings
